SetterGuy - Try building yourself a larger trap using 1/4" or 1/2 mesh. Or maybe one of each mesh size. Larger traps can catch both juvenile and adult fish. Traps can be with or without tops depending on how deep you want to place the tarps. If you place wing net leads in front of the trap opening it will catch more fish per set period.

I also built my own small trap net. I fish them baited and unbaited. They catch quite a few perch 3" to 8" plus most anything in the pond except LM bass. The bigger traps will even catch walleye and SMB up to 16". All traps are fished on the bottom parallel to shore up to 3ft-4ft deep similar to that described by esshup. Evidently at night, lots of fish some of them large cruse the shallow shoreline areas looking for food.
See some of my traps in my PBoss article May-Jun 2015 pg 28-30. "Sampling Your Pond Fish" Pt 1of2.
See these links for just two ideas.
